Diamond Seal: Delta DIAMOND Seal Technology utilizes a ceramic disc valve with a real diamond coating to produce a faucet that will last up to 5 million uses. That's an amazing 10 times the industry standard, guaranteeing a lifetime of leak-free, trouble-free performance.

Watersense Certified Product: Through a number of technologies and innovations, Delta’s Watersense faucets achieve the impossible: A faucet that feels like more water, while actually conserving water. There are many advantages to this beyond helping protect our nation’s water resources. First, Delta’s Watersense faucets splash less; you won’t have to wipe your counters as much. Second, they use less hot water, preserving your hot water supply and reducing associated water-heating costs. Third, you will feel a little less guilty leaving the water running for longer periods.

Great design; quality is mediocreThe Dryden design (whole collection) is very modern and eye appealing. But the materials and quality are not top-shelf. I recently bought the American Standard Town Square collection for the kids' bathroom...this stuff is rock-solid, heavy, beautiful workmanship. I know Kohler is much the same, just pricier. In future, I will stick to AS and Kohler. The hollow base and P.E.T. supply lines on this Dryden faucet scream...cheap! Function is fine, and the toilet-tissue holder is awesome with its swing-up arm, but again, for fixtures that get touched and used every-day...buy the best quality possible. Mark in NY
